Today marks the worldwide premiere of Tron: Legacy. Let's take a look at one of the most important but commonly overlooked element of the ground-breaking Sci-Fi film: the music.

And if you are asking why, there's two word for your question: Daft Punk.

The eccentric electronic music duo (consisting of French musicians Guy-Manuel de Homem-Christo and Thomas Bangalter) not only composed 24 tracks for the film, but also made their cameo in the film as two MP3 programs (the equivalent of disc jockeys) at the End of Line Club. For those who enjoyed Interstella 5555: The 5tory of the 5ecret 5tar 5ystem, the feature-length Japanese animated musical film set to the music of musical duo's "Discovery" album, it is no doubt unnecessary to further explain the significance of their work on a musical score. Belonging to a generation beyond the influence of the original Tron apart from some vague memory of the disc-throwing scenes with weird digital effects, the primary drawing factor for us to the long-awaited follow-up would be the electronic wizardry of Daft Punk. And from what we have gathered from the various trailers and promotional videos, the unique signature of the duo seems to have imprinted themselves all over the film. Check out the below promotional video showcasing "Derezzed", one of the tracks made for the film.

And if you just can't get enough of that catchy tune, here's the official video of the track, featuring a mix of Tron aesthetics both old school and modern, with a surprising cameo by Olivia Wilde her self.
